HOW WOULD THIS MUFFLER TIP FIT ON A STOCK MUFFLER? I CANT FIGURE IT OUT

nicefighter80

well if you go to big you can lose power, i bleive most catbacks are 2.25 inch and for a choice of muffler up to you, do you want loud or quiet?

flowmaniacscrew

i want it to be deep tone.
quiet at low rpms.
loud when you gas it.

i was planning to get Apexi N1.-cause i like the way it looks-.
Apexi Ws2 has the best sound but the look i dont really like. and its expesive for just muffler. same as Apexi N1.

wanted Megan Drift Spec Catback- but they dont make EM1 models. dont sell Universal Muffler of Megan Drift. only Megan Gt.

i'm just planning to get a stock look. Flowmaster series- 40 or 60.

plus with big exhaust tip my MOM will kill me. yes i'm still living with my mom. i'm just 17! lol


So 2.25inch?
so should i get the same measure for the muffler?
would it be okay to get 2.5 and wield it onto 2.25 piping?

ScoobySTI

wouldnt it not change much if u match the size of the header and the piping of the catback?

On any N/A motor its not suggested to go beyond 2.25". Because you lose back pressure and therefore lose low end torque. Thats why the most ideal size would be 2.25"

I'm not going to directly answer your question, but I suggest you read up on scavenging and exhaust velocity and how they affect your exhaust system.

Basically, you aren't strictly after flow. By having a smaller pipe, the velocity of the exhaust gases increases and it will actually suck more exhaust gas out of the engine, making the engine more efficient. This only applies to all motor NA engines. If you put a turbo on, you want to dump your exhaust as fast as you can to spool the turbo faster.

okay. so whats the point of installing a catback?

just SOUND?

flowmaniacscrew

whats the point of installing a aftermarket catback?

SOUND only?

people say it does feel very very little stronger..

When choosing what size piping to go with on exhaust, you have to balance flow capacity and velocity. You want the exhaust exiting at the highest velocity possible while keeping backpressure at a minimum level. If that confuses you, here's an example I learned from. When water comes out of a garden hose, it seems to come out slow. But, as soon as you place your thumb over the hole, the water jets out. By decreasing the outlet size, you have optimized the velocity of the water flow.

Now when the representative told you that your car would lose power, it is due to the same reason as the garden hose example. The smaller outlet that your exhaust has now allows for the exhaust velocity to be relatively high than if you had a 2.5" system. The problem with stock exhaust is backpressure (flow capacity). When you are in the upper RPM's, you begin to suffer from backpressure because of the small diameter exhaust. When you increase the size of your exhaust, you reduce the backpressure that you originally felt in the upper RPM's by increasing the flow capacity.

So long story short, 2.25" exhaust is a good upgrade for you

So all i need to change is the EXHAUST?
not the PIPING?

or i need to do the whole catback 2.25".

Comment on your backpressure. You say when i'm high rpm i suffer back pressure. but dont i need back pressure too? since my ENGINE isnt HIGHLY UPGRADED?

btw thanks you explain it well.

ninjaturtleEG

are you serious?

ps megan drift spec is REALLY loud.

flowmaniacscrew

Hopefully Deep Tone...idc how loud it is or not.
i just want a DEEP *** TONE. dont want fart cannon!

ninjaturtleEG

you have to get an EXHAUST with the right PIPING is what he meant. If you get a loud one, you will get annoyed eventually and all your neighbors will be pissed not to mention girls dont think its cool. loud exhausts only attract men.

flowmaniacscrew

my sexxy body/face does all the attracting when it comes to girls. lol j/k.
loud or not i like deep tone. and what you say is true. loud exhaust get so annoying. drove my cousin's car..omfg..his exhaust was so foken loud. it got so annoyed. i drove like 1 block down the street and i was like "fok this its annoying drove it back...took the bike" went like 0-60 like a LAMBO lol

ninjaturtleEG

if you dont care about cops being on ur *** everyday, then get greddy evo 2 or megan. i had a megan drift spec on my 240sx and it was LOUD and deep but i got pulled over almost everyday and one time i even got pulled over 3x in one day. i was like f*ck that, sold my 240 and got a stock honda =]

flowmaniacscrew

aha yeah. but ummmmm are you able to answer any of my questions?
all the way up there!!!!.

i want to get a Turbo car. what i can afford is a Srt-4 or Wrx.

dont want Gst or Gsx cuz my brother has a Gst. its strong at low end but shoo top end is hella weak. my em1 kept up LMFAO. it just has intake with me and 2 other fat people. i can't believe i kept up! now i have jdm b16a. it feels a little stronger. i want to race'em again see how close i am to winning.

but yeah...are u able to help me on my questions. this forum wasnt really about LOUD EXHAUST.

mortificationrock

Just trying to understand that gave me a HEADACHE!

flowmaniacscrew

Lol. i should try to explain a little better.

ninjaturtleEG

yah pretty much if ur car is n/a, a catback is pretty much pointless other than making your car loud. performance gains are minimal. If ur car was turbo'd than catback would make a huge difference.

mortificationrock

WTF???


/thread

flowmaniacscrew

i agree with you on that.

brother has intake and catback on his GST.

now he runs 5.7 0-60.

stock was like 6.5-6.6 if good launch with shift.

flowmaniacscrew

I MADE A PICTURE..

after seeing the picture plz reply my Question.

Question: Will that mess up airflow?

mortificationrock

?????

flowmaniacscrew

NVM

mortificationrock

Seems like a pic of a email...wtf? is your point?

I told u already. Get a 2.25" catback. Go to a muffler shop and get 2.25" custom piping and add a muffler of your choice. Simple.
